Tannic Acid Modulates Voltage-gated K+ Channels to Promote Neuritogenesis in Neuronal N2A Cells.

In a previous report, we showed that voltage-gated K+ (Kv) Kv1 and Kv2 channels are involved in cAMP-induced neuritogenesis of mouse neuronal N2A cells. In this report, we examined the effects of tannic acid (TA) on Kv channels and neuritogenesis in N2A cells. TA (15 μM) mildly enhanced Kv currents at -30 to -20 mV but strongly inhibited Kv currents at higher voltages, causing a preferential activation of currents at low voltages.

PD-1 cis-targeted IL-2v in combination with radiotherapy inhibits lung cancer growth and remodels the immune microenvironment.

Background: More efficient therapeutic options for non-small cell lung cancer (NSCLC) are needed as the survival at 5 years of metastatic disease is near zero. In this regard, we used a preclinical model of metastatic lung adenocarcinoma (SV2-OVA) to assess the safety and efficacy of novel radio-immunotherapy combining hypofractionated radiotherapy (HRT) with muPD1-IL2v immunocytokine and muFAP-CD40 bispecific antibody.

Methods: We evaluated the changes in the lung immune microenvironment at multiple timepoints following combination therapies and investigated their underlying antitumor mechanisms.

Exploring novel immunotherapy in advanced esophageal squamous cell carcinoma: Is targeting TIGIT an answer?

Esophageal squamous cell carcinoma (ESCC) is a prevalent and highly lethal malignancy in Asia. Recent advancements in immune checkpoint inhibitors (ICIs) have markedly transformed the systemic therapy landscape for ESCC. Anti-PD-1-based combination with chemotherapy or with ipilimumab, an anti-CTLA-4 antibody, have been established as the new standard first-line treatments for patients with advanced ESCC.

Clinical Trial: Precise Administration of Sucralfate Powder in Prevention of Delayed Postpolypectomy Bleeding. A Randomized Controlled Trial.

Background/aims: Delayed postpolypectomy bleeding occurs in approximately 1% to 2% of all patients undergoing colonoscopic polypectomy, and this rate increases to 6% in patients with large (>2 cm) colon polyps. Sucralfate can protect the mucosa and promote its healing. This study was conducted to investigate whether colonoscopic spraying of sucralfate powder on polypectomy wounds can prevent delayed postoperative bleeding.

Assessment of psychological health effects of nurses during 2022-2023 of the COVID-19 pandemic: a descriptive study in Southern Taiwan.

Background: Nurses on the frontlines of the pandemic have increased workloads, burnout, and virus exposure, leading to mental health challenges and a lack of resources for patient care. Mental health support for nurses during the COVID-19 outbreak has become a priority. This study evaluated psychological health outcomes of among nurses during the 2022-2023 COVID-19 pandemic in Taiwan, focusing on personal and work-related fatigue as key contributors to emotional distress.
